transfer theory, the energy donor successfully endows ENBOS with significantly enhanced NIR absorbance and photon utility, which in turn lead to ENBOS more easily activated and generating more O2-• in deep tissues, that thus dramatically intensifies the type I PDT againsthypoxic deep tumors. Moreover, benefiting from the dyad cationic feature, ENBOS achieves superior "structure-inherent targeting"
We synthesized a boron‐dipyrromethene (BODIPY)/Nile Red hybrid probe capable of selectively recognizing fluidity changes in the endoplasmicreticulum (ER) membrane due to its preferential localization to the ER and strong energy transfer from BODIPY to the Nile Red moiety, emitting only in nonaqueous environments. ER membranefluidity in HepG2 cells was markedly reduced by a cell model of metabolic
common fluorophores. By simply appending a 1,4-diethyl-decahydro-quinoxaline (DQ) moiety onto the conjugated structure, we introduced a vibronic backbone that could facilely expand the Stokes shifts, emission wavelength, and photostability of 11 different fluorophores by more than 3-fold. This generalizable method could significantly improve the imaging efficiency of commercial fluorophores. As a demonstration

immobilization of the mono‐thiol functionalized β‐CD on PEGA resin via a disulfide bond, enabling solid‐phase elaboration of the remaining six primary amines. To showcase the potential of this method, the amines were elaborated to tripeptides through standard Fmoc‐peptide chemistry. A small library of CD‐tripeptide conjugates was generated which, when reduced from the solidsupport, could be tagged at the
