Due to the boost of CO_(2)/NO_(x)emissions which cause environmental pollution,processes that remove such pollutants from flue gas have attracted increasing attention in recent years.Among these technologies,biological CO_(2)/NO_(x)emission reduction has received more interest.Microalgae,a kind of photosynthetic microorganism,offer great promise to convert CO_(2)/NO_(x)to biomass with high content of lipid and protein,which can be used as feedstock for various products such as biodiesel,health products,feedstuff and biomaterials.In this paper,biological CO_(2)/NO_(x)removing technologies by microalgae,together with the products(such as biofuel and protein)and their economic viability are discussed.Although commercial applications of microalgae for biodiesel and protein products are hampered by the high production cost of biomass,the use of CO_(2)/NO_(x)from flue gas as carbon and nitrogen sources can reduce the cost of biomass production,which makes these technologies more competent for real-life applications.Moreover,it is projected that the increasing in CO_(2)allowances will lead to further reduction in the cost of biomass production,which especially favors related products with lower values such as biodiesel.Furthermore,by combining various process optimization and integration,biorefinery is proposed and considered as the crucial component for the sustainable and economically feasible bulk applications of microalgae biomass.

Tremendous progress has been made on aromatic fusion of acenaphthylene towards organic semiconductors.However,scarce studies focus on the functionalization of acenaphthylene without resort to aromatic extension,although vinylene double bond is highly reactive ascribed to the ring strain of the fused cyclopentene.Herein,for the first time we employ copper-promoted domino cyanation/Ullmann coupling to achieve a series of difunctionalized acenaphthylene imides(ANIs)with varied optoelectronic properties.Both Ullmann homocoupling and crosscoupling can be combined with cyanation for difunctionalization of ANIs.The introduction of cyano groups influences oppositely not only the energy levels but also the antiaromaticity of the fivemembered rings in ANIs relative to the dimethylamino substituent due to the electron donating or withdrawing effects.By altering the functional units,the optical and electrical characteristics have been tailored rationally;thus p,n or ambipolar semiconducting properties can be achieved for the ANI derivatives.This article opens up possibilities to the development of organic semiconducting materials based on ANIs without aromatic extension,which is promising for applications in organic electronics.

Aromatic six-membered imides suffer the introduction of bulky substituents at the imide positions due to the formation of isoimides and low reactivity,preventing from the investigation of the intrinsic molecular properties.Here,we found a highly efficient alcohol-promoted rearrangement from isonaphthalimide to naphthalimide under acid or basic nonaqueous conditions,which can be regarded as model compounds for aromatic six-membered imides.We proposed two-step nucleophilic substitutions in the isomerization mechanistic pathways that were verified by the separation of a key intermediate.Furthermore,in-situ ^(1)H NMR exhibited the first-order kinetics for the isoimide loss process.Finally,the alcohol-promoted isoimide-imide rearrangement was extended to a palladium-catalyzed one-pot domino carbonylation reaction toward sterically crowded aromatic six-membered imides.

基于有机π共轭体系的一维自组装微纳米材料(1D-MNMs)具有较少的散射电荷传输、尺寸适中、易于制备等优点,可以方便地构筑集成微电路.虽然基于p沟道或n沟道有机半导体的一维自组装微纳米材料已经取得了巨大的进展,但遗憾的是,迄今为止,基于双极性有机半导体的一维自组装微纳米材料还非常缺乏.本文利用物理气相传输法,制备了基于6,13-双氰基并五苯(DCP)的一维滑移堆积新型自组装微纳米材料,其表现出良好的双极性电荷传输特性,电子和空穴迁移率分别达到0.34和0.38 cm2 V^(-1)s^(-1),是一维自组装微纳米材料中最好的双极性电荷传输特性之一.此外,基于双极性DCP的一维自组装微纳米材料构建了互补型反相器,增益可达7,表明其在有机逻辑电路中具有潜在的应用前景.
