ABSTRACT This study examines light‐matter interactions in CsFAPb(Br, I)3 perovskite thin films by analyzing their absorption, reflection, and emission properties using Fresnel‐based OPAL2 simulations. The optical spectra show sharp absorption edges at 1.55 – 1.60 eV for CH3NH3PbI3 and triple‐cation perovskites, which blue‐shift to ∼1.8 eV with ...

A light‐responsive system with photochromism and excitation‐dependent phosphorescence was constructed by microwave synthesis of nitrogen‐doped carbon dots(N‐CDs), which provides insights into the design and synthesis of CDs with multifunctional optical properties, promoting the application expansion of intelligent responsive materials in the fields of ...

Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes
Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...

We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex
Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.
