1·They engineered it so that one end carries a catalyst-iridium oxide. Bound at the other end are light-sensitive pigments, zinc porphyrins.
他们将其重新编程，使一段带有催化剂——氧化铱，另一端则带有光敏色素锌卟啉。
2·The present paper covers the mechanism of coordination reaction of porphyrins with some metal ions studied by fluorometry and the catalytic mechanism of some catalysts.
本文用荧光光谱法初步研究了卟啉与金属离子配位反应机理和部分催化剂的催化机理。
3·Chemical fossils (e. g. alkanes and porphyrins) are often the only evidence for life in rocks of PRECAMBRIAN age.
化学化石(烷烃和卟啉)是前寒武纪地层中生命存在的唯一证据。
4·The synthesis of natural cyclic tetrapyrroles which include porphyrins, chlorins, bacteriochlorins, isobacteriochlorins and corrins is presently one of the most attractive fields in organic synthesis.
天然环状四吡咯化合物包括卟啉、卟吩、细菌卟吩、异菌卟吩以及可啉等类物质，其合成研究是目前有机合成领域的热点之一。
5·Porphyrins are a class of macrocyclic compounds with rigid conjugate structure, it can easily emit strong fluorescence under irradiation.
卟啉是一类具有刚性的共轭大环类化合物，在光的照射下，易被激发，产生强荧光。
