Abstract:
Two organic-inorganic iodoargentate hybrids, [(HPBI)·(MeCN)][Ag3I4] (1) and [MPBI][Ag3I4] (2) (HPBI+ = 1-proton-2-phenylbenzimidazolium, MPBI+ = 1,3-dimethyl-2-phenylbenzimidazolium), have been synthesized. They exhibit structure-dependent photochromism with fast response and wide color range (from colorless to purple and dark green in 1 and 2, respectively), which are attributed to a substantially reversible photolysis for 1 and dual photolysis and photoinduced secondary ET for 2.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
