Halogen atom effect on organic luminescence materials incorporating arylsulfonylated phenothiazine as the central unit was investigated in both solid state and organic solution. New organic solids with very weak C-halogen⋯π interactions are constructed, in which the packing style totally avoids the face-to-face stacking. Consequently, a high solid luminescent efficiency (81.37%) is obtained from a fluorine-substituted organic molecule crystal. The halogen atom effect on photocatalytic reaction was evaluated using arylsulfonylated phenothiazines, which catalyzed dehydrogenative coupling of amines to imines by simple blue light irradiation of the acetonitrile solution under aerobic atmosphere. The chlorine- substituted photocatalyst exhibited a higher reactivity than other ones, providing a preliminary insight for rational photocatalysts modification.

研究了在固态和有机溶液中卤素原子对以芳基磺酰化吩噻嗪为中心的有机发光材料的影响。构造了具有非常弱的C-卤素⋯π相互作用的新有机固体，其中的堆积方式完全避免了面对面的堆积。因此，由氟取代的有机分子晶体获得高的固体发光效率（81.37％）。使用芳基磺酰化的吩噻嗪评估卤素原子对光催化反应的影响，其通过在有氧气氛下对乙腈溶液进行简单的蓝光照射来催化胺与亚胺的脱氢偶联。氯取代的光催化剂显示出比其他催化剂更高的反应活性，
