Biological substrates and organelle multi-targeted photosensitizers for ultra-efficient cancer treatment through photodynamic therapy (PDT) are highly desirable. Herein, a multiple pyridinium-anchored photosensitizer containing the triphenylamine unit, TPA-2PI, has been designed and utilized for DNA and mitochondria dual-targeted two-photon-excited bioimaging and PDT. TPA-2PI possesses an ultrahigh ABDA consumption rate of 194.

Herein, in this contribution, we have developed a 2-dicyanomethylenethiazole-based D-π-A structured near-infrared photosensitizer (TTR). TTR exhibits near-infrared emission (704 nm), a large Stokes shift (200 nm), and smaller ΔE- (the energy gap between S and T) (0.

Chrysanthemum morifolium, valued as an ornamental species given the diversity of its inflorescence form, is viewed as a model for understanding flower development in the Asteraceae. Yet, the underlying regulatory networks remain largely unexplored.
