摘要

冷结晶通常发生在聚合物中，但很少在小分子晶体中发现。本文报道了第一个具有冷结晶性质的光致发光二阶非线性光学分子晶体，该晶体在358k加热时显示出结晶，并且具有与KH2PO4相当的绿色光致发光和强的二次谐波响应。

A photoluminescent second-order nonlinear optical molecular crystal with cold crystallization†

Cold crystallization occurs commonly in polymers but is rarely found in small molecular crystals. Here, we report the first photoluminescent second-order nonlinear optical molecular crystal with cold crystallization, which shows crystallization upon heating at 358 K as well as green photoluminescence emission and strong second harmonic generation response with intensity comparable to that of KH₂PO₄.
