Energy transfer can leverage the enormous potential of excited-state reactivity. Through “indirect excitation” of substrates, otherwise elusive reactivity modes can be switched on, allowing for, e.g., cycloadditions, fragmentations, rearrangements, or challenging organometallic steps. This perspective recaps almost 70 years of energy transfer in organic chemistry, highlighting the way it evolved, as well as recent developments in the field of visible-light photocatalysis. Building upon the photophysical fundamentals, diverse applications and directions of energy transfer catalysis are pointed out.

三重态能量转移光催化：开启新的台阶

能量转移可以利用激发态反应的巨大潜力。通过底物的“间接激发”，可以打开其他难以捉摸的反应模式，例如允许进行环加成，断裂，重排或具有挑战性的有机金属步骤。这种观点回顾了近70年来有机化学中的能量转移，突出了它的发展方式以及可见光光催化领域的最新进展。在光物理基础上，指出了能量转移催化的各种应用和方向。
