摘要:
为拓展具有高稳定性及能带可调性的氮杂多并苯材料的结构,将O/S原子镶嵌在氮杂六并苯材料骨架中,制备O/N、S/N双原子混杂的六并苯材料。研究结果表明,S/N混杂六并苯(DATH)吸收峰及发射峰相对于O/N混杂六并苯(DAOH)分别红移16 nm及68 nm。同时,S原子的引入大大淬灭了体系荧光,DAOH的二氯甲烷溶液中荧光强度(Φf =0.378)为DATH二氯甲烷溶液(Φf =0.094)的4倍。电化学研究表明,相对于DAOH,DATH更易被氧化。两类材料的研究为未来氮/氧与氮/硫双原子混杂并苯材料有机电子领域应用打下基础。
Abstract:
To develop the highly stable and band gap adjustable azaacene structures, oxygen/sulfur(O/S) atoms have been successfully inserted into the skeleton of azahexacene to prepare oxygen/nitrogen(O/N) and sulfur/nitrogen(S/N) heteroatom-containing hexacenes. The results showed that the absorption peak and emission peak of S/N heteroatom-containing hexacene (DATH) was red-shifted by 16 nm and 68 nm, respectively, compared to those of O/N heteroatom-containing hexacene (DAOH). Meanwhile, the fluorescence of azahexacene was greatly quenched when the S atom was introduced into the skeleton of azahexacene. The fluorescence intensity of the compound DAOH in CH2Cl2 was 4 times higher than that of the compound DATH. Moreover, the cyclic voltammogram shows that DATH is more easily oxidized than DAOH. The study lays a foundation for the application of N/O and N/S heteroatom-containing acenes in the field of organic electronics.
