Telluride materials possess distinctive advantages, including the high theoretical volume capacity and electrical conductivity,rendering them promising candidates for a range of energy storage and optoelectronic applications [1]. Heterogeneous compositions and interfaces in heteronanostructures have significant implications on the electron transport, magnetic coupling, and phonon scattering, thereby promoting the performances in photocatalysis, and thermoelectrics [2]. Combining the unique properties of tellurides with the superior characteristics of heteronanostructures, telluride-based heteronanostructures offer tailored functionalities for diverse applications such as energy storage, optoelectronics, and catalysis.Among these, one-dimensional (1D) axially segmented telluridebased heteronanostructures, which optimize the synergistic effect between compositions and interfaces, has garnered significant attentions.

As an emerging donor building block,naphthodithiophene（NDT） is causing more concerns in the field of organic semiconductors.With the rigid and coplanar molecule structure,NDT will exhibit more application space relying on its own advantage for facilitating the charge carrier transport.In this review article,we have summarized the development progress on the NDT-based donor materials for solution processed organic solar cells.Discussions and comments on those representative NDT type materials about structure and property are also presented.

The generation of chirality in supramolecular structures from achiral building blocks has remained a challenge for a long time.In this study,we present a vortex-assisted chiral supramolecular polymerization from a series of achiral C3-symmetric monomers,where the mechanism of symmetry-breaking is systematically investigated.By increasing the supersaturation,at the early stage of nucleation and growth,highly ordered assemblies can be generated as the initial chiral nuclei.Meanwhile,chiral assemblies from high supersaturation are hard to interwind into clusters,where clusters as nuclei are not conducive to being fractured by sheer force of vortex fluid.Therefore,it is concluded that chiral assemblies in the nucleation stage possess low energy barrier,so that chiral nuclei could be fractured and replicated by the vortex.By enlarging the initial chiral bias,the major chiral nuclei can evolute into the final chiral polymers.

Multifunctional core-shell nanostructures formed by integration of distinct components have received wide attention as promising biological platforms in recent years. In this work, crystalline zeolitic imidazolate framework-8 （ZIF-8）, a typical metal-organic framework （MOF）, is coated onto single gold nanorod （AuNR） core for successful realization of synergistic photothermal and chemotherapy triggered by near-infrared （NIR） light. Impressivel）~ high doxorubicin hydrochloride （DOX） loading capacity followed by pH and NIR light dual stimuli-responsive DOX release can be easily implemented through formation and breakage of coordination bonds in the system. Moreover, under NIR laser irradiation at 808 nm, these novel AuNR@MOF core-shell nanostructures exhibit effective synergistic chemo-photothermal therapy both in vitro and in vivo, confirmed by cell treatment and tumor ablation via intravenous injection.

The effective design and synthesis of novel small-molecule donors(SMDs) is extremely essential for the in-depth study of the scientific problems of bulk heterojunction morphology and the improvement of photovoltaic performance in organic solar cells(OSCs). Importantly, developing a series of donors with different conjugated central donor(D) units is a remarkable strategy to obtain high-performance donors. Herein, two acceptor-donor-donor-acceptor(A-D-D-A) type oligomeric donors 2DTBDT and2DTBDT-2T with two dithieno[2,3-d:2,3-d’]benzo[1,2-b:4,5-b’]dithiophene(DTBDT) as D units, without and with bithiophene as the π bridge respectively are designed and synthesized successfully. The central linked-DTBDT unit can provide a larger conjugated plane and promote π electron delocalization, which can effectively improve π-π interactions between donors and regulate the crystallinity. And we found that the π bridge provided 2DTBDT-2T with 12.31% efficiency that is already a high efficiency in OSCs,whereas 2DTBDT with merely 3.63% efficiency, both with 2,2-((2Z,2 Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]thiadiazolo[3,4-e]thieno[2,"3 ’:4,5 ]thieno[2,3 :4,5]pyrrolo[3,2-g]thieno-[2,3 :4,5]thieno[3,2-b]indole,10-diyl)bis(methanylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene)) dimalononitrile(Y6) as the acceptor. We conjecture that the main reason for the different device performance may be ascribed to the different molecular stacking orientation of the oligomeric donors and morphology features of the donors:Y6 blend films. Compared to the predominant face-on orientation of the 2DTBDT neat film, the 2DTBDT-2T neat film performed a preferential edge-on orientation, which obtained a smoother surface, stronger crystallinity and more uniform phase separation in the 2DTBDT-2T:Y6 blend films with nanofiber structure, which delivered higher and more balanced carrier mobilities, the more efficient exciton dissociation and reduced biomolecule recombination, therefore obtaining better power conve

Polarization means symmetry loss for light vibration along light propagation direction,which is a particular physical property of light.The polarization state is indecipherable for most polarization-insensitive detectors.Polarization can carry and differentiate light information,and can be used in polarized light detection,polarization imaging and encryption communication[1].Photodetectors are the core component of some photoelectric devices[2]used in biomedical sensing,remote sensing,military field,etc.

The family of perovskite materials derived from the crystal structure of the mineral CaTiO3,which was first reported in 1839[1].Then a series of materials with perovskite structure were discovered.Most perovskite materials have the ABX3 stoichiometry,in which A is monovalent or divalent cation,B is divalent or tetravalent cation,and X is monovalent or divalent anion.Perovskite materials play important roles in various functional devices due to their unique optical,electronic and optoelectronic properties.Inorganic perovskites such as BaTiO3 and PbTiO3 have been widely used in ferroelectric and piezoelectric devices,actuators,capacitors,and nonlinear optical devices[2].The emergence of organic–inorganic hybrid perovskites such as CH3NH3PbI3 triggers a new wave of research about perovskite-based devices,such as solar cells,light-emitting diodes(LEDs),photodetectors,lasers,and field-effect transistors[3,4].Motivated by the outstanding performance of perovskite materials,a variety of perovskite derivatives were developed,such as two-dimensional perovskites,double perovskites,and vacancy-ordered perovskites[5,6].
