A novel 4,4-difuoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) copolymer with diethynylbenzene has been synthesised, and its ability to act as a photosensitiser for the photocatalytic generation of hydrogen was investigated by time-resolved spectroscopic techniques spanning the ps- to ns-timescales. Both transient absorption and time-resolved infrared spectroscopy were used to probe the excited state dynamics of this photosensitising unit in a variety of solvents. These studies indicated how environmental factors can influence the photophysics of the BODIPY polymer. A homogeneous photocatalytic hydrogen evolution system has been developed using the BODIPY copolymer and cobaloxime which provides hydrogen evolution rates of 319 μmol h⁻¹ g⁻¹ after 24 h of visible irradiation.

合成了具有二乙炔基苯的新型4,4-difuoro-4-bora-3a，4a-diaza-s-indacene（BODIPY）共聚物，并通过时间催化研究了其作为光敏剂用于光催化制氢的能力。解决了跨越ps到ns时标的光谱技术。瞬态吸收和时间分辨红外光谱均用于探测该光敏单元在各种溶剂中的激发态动力学。这些研究表明环境因素如何影响BODIPY聚合物的光物理性质。已经使用BODIPY共聚物和钴肟开发了均相的光催化氢释放系统，其在可见光照射24小时后提供了319μmolh ^-1 g ^-1的氢释放速率。
