Phenothiazines with a dimesityl boron moiety, a new class of aminoboranes with B-N linkage, were synthesized. These aminoboranes exhibited interesting photophysical behavior including aggregation-induced emission (AIE), mechanochromism (MC), mechanoluminescence (ML), and a mega Stokes shift (up to 312 nm in hexane). The solid-state emission of the aminoboranes could be switched reversibly by grinding-fuming processes. Furthermore, the phenothiazine derivative with a bromo and an arylborane group at 3- and 7-positions exhibited bright mechanoluminescence.
合成了带有二甲基硼部分的吩噻嗪，这是一类具有B-N键的新型氨基硼烷。这些氨基硼烷表现出有趣的光物理行为，包括聚集诱导发光（AIE）、机械变色（MC）、机械发光（ML）和大斯托克斯位移（在己烷中高达312 nm）。氨基硼烷的固态发射可以通过研磨-熏蒸过程可逆地切换。此外，在3位和7位带有溴和芳基硼烷基团的吩噻嗪衍生物表现出明亮的机械发光。
