A new class of oxygen indicators is described. Platinum(II) and palladium(II) complexes of azatetrabenzoporphyrins occupy an intermediate position between tetrabenzoporphyrins and phthalocyanines and combine features of both. The new dyes are excitable in the red part of the spectrum and possess strong room-temperature NIR phosphorescence. Other features include excellent spectral compatibility with the red laser diodes and 632.8 nm line of He-Ne laser, excellent photostability, and significantly shorter decay times than for the respective meso-tetraphenyltetrabenzoporphyrins. Applicability of the complexes for optical oxygen sensing is demonstrated.
描述了一类新型的氧指示剂。氮杂四苯并卟啉的铂（II）和钯（II）配合物位于四苯并卟啉和酞菁之间，兼具两者的特点。新型染料在光谱的红色部分可被激发，并具有很强的室温近红外磷光。其他特点包括与红色激光二极管和氦氖激光的 632.8nm 线具有极好的光谱兼容性、极好的光稳定性以及比相应的中位四苯基四苯并卟啉短得多的衰减时间。该配合物在光学氧传感中的应用得到了证明。
