Ultrafast Radiative Recombination of Singlet Excitons in Conjugated Polymer Aggregates Modulated by the Intrachain Dissociation–Interchain Delocalization Competition

Abstract We readily modulated relaxation pathways of singlet (S1) excitons in push–pull conjugated polymer (CP, D18) aggregates by controlling the spin-coating process. Transient absorption spectroscopy results reveal that intrachain (localized) S1 excitons are efficiently conver...

Satisfaction in Generative AI Supportive Interaction: The Roles of Perceived Usefulness, Perceived Supportive Interaction, and Reliance Tendency

Generative AI is increasingly used for task support, idea development, learning, problem solving, and emotional support.This study examined the associations of perceived usefulness and perceived supportive interaction with interaction satisfaction and assessed whether reliance te...
