An asymmetrically substituted squaraine ASQC bearing a 9-carbazyl substituent exhibits an extremely deep HOMO energy level of −5.46 eV and a relatively low bandgap of 1.65 eV, hence renders solution-processed organic solar cells with an impressive Voc of up to 1.12 V and a PCE of 2.82%.

few newly synthesized thienosquaraines are presented. These properties are compared to those of the commercial 2,4‐bis[4‐(N,N‐diisobutylamino)‐2,6‐dihydroxyphenyl]squaraine. The stability of the radicalions formed in electrochemical processes strongly affects these properties, as shown by cyclic voltammetry, in situ spectroelectrochemistry, and quantum chemical calculations. Furthermore, all of the

Compared to bis(N,N-diisobutylanilino)squaraine, both symmetrical and unsymmetrical N,N-diarylanilino squaraines show markedly broader absorption bands in solution than their N,N-dialkylanilino squaraine counterparts: the full width at half-maximum (fwhm) for N,N-diarylanilino squaraines range from 1280–1980 cm–1, while the fwhm value
我们报告N,对称方酸菁染料的新衍生物N-二芳基具有高溶解度和高的吸收率(ε= 0.71-4.1×10苯胺取代基5中号-1 厘米-1在红色太阳光谱区域)(λ最大= 645-694 nm)使其成为有机光伏(OPV)应用的有希望的候选者。还制备了非对称的N,N-二异丁基苯胺基和N,N-二苯基苯胺基(二苯基氨基)方胺,相对于它们的对称对应物,它们给出了蓝移的吸收光谱(λmax = 529–535 nm)。与双(N,N-二异丁基苯胺基)方酸相比,对称和不对称的N,N-二芳基苯胺方酸在溶液中的吸收带比N,N-di烷基苯胺方酸的对应物要宽得多:N,N-二芳基苯胺方酸的半峰全宽(fwhm)为1280–1980 cm –1,而N,N-二异丁基苯胺基对苯二酚的fwhm值仅为630 cm –1。N,N-二芳基苯胺类方酸薄膜的吸收带进一步扩大到2500-3300 cm -1。N,N-Di芳基苯胺类方括号是荧光的,

model cells by an organic semiconductor–electrolyteinterface. Our photoactive layer consisting of an anilino-squaraine donor blended with a fullerene acceptor is supporting the growth of the neuronal model cell line (N2A cells) without an adhesion layer on it and is not impairing cell viability. The transient photocurrent signal upon illumination from the semiconductor–electrolyte layer is able to trigger
