本文详细研究和讨论了温度、压力、溶剂和底物浓度对几种对映体和非对映体的光化学反应的影响。这些与熵相关的外部因素，在激发态下操纵弱的电子和空间相互作用，动态地控制不对称光化学反应的立体化学结果，甚至切换产物的手性。对“熵化学”的全局观及其潜在的应用也进行了讨论。
Abstract The effects of temperature, pressure, solvent, and substrate concentration upon several enantio- and diastereodifferentiating photochemical reactions have been investigated and discussed in detail. These entropy-related external factors, which manipulate the weak electronic and steric interactions in the excited state, dynamically control the stereochemical outcome of asymmetric photochemical reactions, and even switch the product chirality. A global view on the "entropy chemistry" and its potential applications are also discussed.
