lower-lying absorption is assigned to the S0 → S2(ππ*) transition and is red-shifted upon increasing the number of thiones; the lowest-lying excited state is ascribed to a transition-forbidden S1(nπ*) configuration. All nS-PDIs are non-emissive in solution but reveal an excellent two-photon absorption cross-section of >800 GM. Supported by the femtosecond transient absorption study, the S1(nπ*) → T1(ππ*)
在本研究中,发色团 3,4,9,10-苝四羧酸二亚胺 (PDI) 在酰亚胺 N 位点用苯基取代基锚定,然后进行硫化,得到一系列硫酮产物1S-PDI-D , 2S- cis - PDI-D、2S-反式-PDI-D、3S-PDI-D和4S-PDI-D分别具有n = 1、2、3 和 4 硫酮。光物理性质取决于锚定硫酮的数量,其中观察到的显着较低吸收分配给 S 0 → S 2(ππ*) 跃迁并且随着硫酮数量的增加而红移;最低激发态归因于禁止跃迁的 S 1 ( n π*) 构型。所有n S-PDI在溶液中都是不发射的,但显示出 > 800 GM 的出色双光子吸收截面。在飞秒瞬态吸收研究的支持下,S 1 ( n π*) → T 1 (ππ*) 系统间穿越 (ISC) 率 > 10 12 s –1,导致 ∼100% 三重态种群。最低的 T 1 (ππ*) 能量计算为1S-PDI-D > 2S- cis-PDI-D
