It is a challenge to develop single polymer-based photocatalyst for overall water splitting without adding sacrificial agents due to the insufficient driving force for charge separation and the lack of active sites of organic polymer.Metal oxyhyroxides are widely acted as co-catalyst for photoelectrocatalysis oxygen evolution reaction.Here,we firstly report the peryleno[1,12-bcd]thiophene sulfone-based linear co-polymer PS-5 for photocatalytic overall water splitting by photo-depositing simple and low-cost cocatalyst FeOOH under the visible-light illumination.The density functional theory(DFT)calculations and experimental results indicated clearly that the oxygen vacancies-richβ-FeOOH can effectively promote the separation of photo-generated excitons and provide active sites for photocatalytic oxygen evolution reaction.As a result,the average H_(2)and O_(2)production rates of optimized PS-5/β-FeOOH-0.2M reach at~170 and~76.6μmol h^(-1)g^(-1),respectively,with a stoichiometric ratio at about 2:1.This work provides a simple and low-cost method for the preparation of overall water splitting system based on polymer photocatalyst.

Dye-sensitized solar cells （DSSCs） cannot be developed without the research on sensitizers. As the key of light harvesting and electron generation, thousands of sensitizers have been designed for the application in DSSC devices. Among them, organic sensitizers have drawn a lot of attention because of the flexible molecular design, easy synthesis and good photovoltaic performance. Recently, new record photovoltaic conversion efficiencies of 11.5% for DSSCs with iodide electrolyte and 14.3% for DSSCs with cobalt electrolyte and co-sensitization have been achieved with organic sensitizers. Here we focus on the donor design and modification of organic sensitizers. Several useful strategies and corresponding typical examples are presented.

A distinctive method is proposed by simply utilizing ultrasonic technique in Ti02 electrode fabrication in order to improve the optoelectronic performance of dye-sensitized solar cells （DSSCs）. Dye molecules are at random and single molecular state in the ultrasonic field and the ultrasonic wave favors the diffusion and adsorption processes of dye molecules. As a result, the introduction of ultrasonic technique at room temperature leads to faster and more well-distributed dye adsorption on TiO2 as well as higher cell efficiency than regular deposition, thus the fabrication time is markedly reduced. It is found that the device based on 40 kHz ultrasonic （within 1 h） with N719 exhibits a Voc of 789 mV, Jsc of 14.94 mA]cm2 and fill factor （FF） of 69.3, yielding power conversion efficiency （PCE） of 8.16%, which is higher than device regularly dyed for 12 h （PCE = 8.06%）. In addition, the DSSC devices obtain the best efficiency （PCE = 8.68%） when the ultrasonic deposition time increases to 2.5 h. The DSSCs fabricated via ultrasonic technique presents more dye loading, larger photocurrent, less charge recombination and higher photovoltage. The charge extraction and electron impedance spectroscopy （EIS） were performed to understand the influence of ultrasonic technique on the electron recombination and performance of DSSCs.

Dye-sensitized photoelectrochemical tandem cells have shown the promise for light driven hydrogen production from water owing to the low cost,wide absorption spectra in the visible region and ease to process of their constitutive photoelectrode materials.However,most photo-driven water splitting photoelectrochemical cells driven by organic dye sensitized solar cells exhibit unsatisfactory hydrogen evolution rate,primarily attributed to their poor light capturing ability and low photocurrent performance.Here we present the construction of a tandem system consisting of an organic blue-colored S5 sensitizer-based dyesensitized photoelectrochemical cell(DSPEC) wired in series with three spectral-complemental dyes BTA-2,APP-3 and APP-1 sensitizers-based dye-sensitized solar cell(DSC),respectively.The two spectral-complemental chromophores were used in DSC and DSPEC to ensure that the full solar spectrum could be absorbed as much as possible.The results showed that the photocurrent of tandem device was closely related to the open-circuit voltage(Voc) of sensitized DSC,in which the tandem configuration consisting of S5 based DSPEC and BTA-2 based DSC gave the best photocurrent.On this basis,tandem device with the only light energy and no external applied electrical bias was further constructed of BTA-2 based 2-junction DSC and S5 based DSPEC and obtained a photocurrent of 500 μA cm-2 for hydrogen generation.Furthermore,I-/I3-was used as a redox couple between dye regeneration and O2 production on the surface of Pt-IrO2/WO3.The strategy opens up the application of pure organic dyes in DSC/DSPEC tandem device.

In this work, two new dyes YK-1 and YK-2 with carboxylic acid and hydroxamic acid as anchoring groups,respectively, in combination with diphenylamine as donor and perylenemonoimide as acceptor were synthesized and applied in p-type dye-sensitized solar cells（p-DSCs） and dye-sensitized photoelectrochemical cells（PEC）. The results showed that the sensitizer（YK-1） based on carboxylic acid displayed a higher conversion efficiency of 0.064% under AM 1.5 solar conditions in p-DSCs. However, it was interesting that the hydroxamic acid based sensitizer（YK-2） on Ni O photocathode displayed better performance in a hydrophilic environment over a broad p H range under visible-light irradiation because of a versatile covalent attachment to Ni O surfaces. This may be ascribed to hydroxamic acid anchors, which have more sites interacting with the surface of Ni O in aqueous solution. This study demonstrates that YK-2 containing hydroxamic acid anchoring group is a promising candidate to achieve highly efficient and stable activity for dye-sensitized PEC system.

Two organic sensitizers(LI-33 and LI-34) with double anchoring units were synthesized and utilized for dye sensitized solar cells(DSSCs), which contained thiophene or vinyl thiophene as π-bridge. The introduction of double anchoring units can change their absorption spectra and energy levels in a large degree, thus, the better light-harvesting ability and the convenient electron transfer along the whole molecule can be obtained. The solar cell based on LI-34 exhibited a broad incident photonto-current conversion efficiency(IPCE) spectrum and high conversion efficiency(η=6.05%) with coadsorbent CDCA.

Since the elucidation that sugar-lectin interactions contribute to the understanding of ‘‘Glycomics' ', how to construct glycosensors with rapid response, excellent sensitivity and selectivity is of intense research interest. Herein, we report the design of three NIR emissive glyco-probes based on diketopyrrolopyrrole(DPPs) conjugated with two(DPPG), four(DPPF-G) and six(DPPS-G) galactose groups. All three molecules could probe lectins with excellent sensitivity and selectivity. The increase of glyco-DPP emission in NIR region upon interaction with lectin is due to the aggregates formation induced by sugar-lectin interactions, which have been verified by dynamic light scattering(DLS) and scanning electronic microscope(SEM) analysis.Due to the multiple glyco-ligands on DPPS-G, it has been successfully used to stain Hep G2 cells through interactions between galactose and asialogly-coprotein(ASGP-R), which are overexpressed on the surface of Hep G2 cells.
