kasha’s rule,which states that all exciton emissions occur from the lowest excited state and are independent of excitation energy,makes high-energy excitons difficult to use and severely hinders the widespread applications of organic photoluminescent materials in the real *** decades,scientists have tried to break this rule to unleash the power of high-energy excitons,but only minimal progress has been achieved,with no rational guiding principles provided,and few applications *** far,breaking kasha’s rule has remained a purely academic *** this paper,we introduce a design principle for a purely organic anti-kasha system and synthesise a series of compounds based on the design *** predicted,these compounds all display evident S_(2) emissions in dilute *** addition,we introduce a highly accurate(over 90%)convolutional neural network as an assistant for the classification of cells using anti-kasha luminogens,thereby providing a new application direction for anti-kasha systems.
