We report herein the reversible mechanochromic luminescence property of (dibenzo[a,c]phenazine-9,14-diylbis(4,1-phenylene))dimethanol (DPAC-OH) where the photoluminescene color changes from blue to blue-green upon grinding, which can be restored upon slow solvent evaporation. 9,14-bis(4-(methoxymethyl)phenyl)-9,14-dihydrodibenzo[a,c]phenazine (DPAC-OCH₃) is synthesized as the control sample to further demonstrate the role of hydrogen bonding in DPAC-OH. The vibration-induced emission (VIE) mechanism and the presence of hydrogen bonding interactions are utilized to account for the mechanochromic phenomenon.

我们在此报告了 (dibenzo[a,c]phenazine-9,14-diylbis(4,1-phenylene))dimethyl ( DPAC-OH ) 的可逆机械致变色发光特性，其中光致发光颜色在研磨时从蓝色变为蓝绿色，可以在缓慢的溶剂蒸发后恢复。合成了9,14-双(4-(甲氧基甲基)苯基)-9,14-二氢二苯并[a,c]吩嗪( DPAC-OCH ₃ )作为对照样品，以进一步证明氢键在DPAC-OH中的作用。振动诱导发射 ( VIE ) 机制和氢键相互作用的存在被用来解释机械变色现象。
