We have investigated light-triggered or catalytically activated precipitation agents and have proposed the name “precipiton” for such molecules or molecular fragments. A phase separation Is induced when the precipiton isomerizes to a low-solubility form. In this paper we describe the first intramolecularly activated precipitons. The isomerization process is induced by intramolecular triplet energy transfer from a covalently attached metal complex. As expected, intramolecular sensitization leads to a more rapid isomerization than can be achieved by intermolecular sensitization at accessible concentrations. Two isomeric bichromophoric precipiton species, each containing [Ru(bpy)3]2+ and 1,2-bis(biphenyl)ethene units covalently linked together by an ether tether, have been synthesized and characterized, and their photochemical properties have been investigated. The rates of photoisomerization of these complexes, [((Z)-1,2-bis(biphenyl)ethene-bpy)Ru(bpy) 2](PF6)2 (2Z) and [((E)-1,2-bis(biphenyl) ethene-bpy)Ru(bpy)2](PF6)2 (2E), were compared to those of their untethered analogues, (Z)-1,2-bis(biphenyl)ethene-OTBS (1Z) and (E)-1,2-bis(biphenyl)ethene-OTBS (1E), where ruthenium sensitization occurred through an intermolecular pathway. Upon irradiation with visible light (lambda ? 400 nm) in degassed solution, 2Z/E and 1Z/E obeyed reversible first-order rate kinetics. The intramolecularly sensitized precipiton 2Z isomerized 250 times faster (k2Z-2E = 1.0 × 10-3 s-1 with a 51% neutral density filter) than the intermolecular case 1Z (k1Z-1E = 0.80 × 10-5 s-1). For 1E and 2E, the isomerization rates were k1E-1Z = 11.0 × 10 -5 s-1 and k2E-2Z = 1.6 × 10-3 s-1, respectively. The average Z/E mole ratio at the photostationary state was 62/38 for 2Z/E and 93/7 for 1Z/E. The impetus for this study was our desire to evaluate the possibility of using metal-binding precipitons that would precipitate only upon metal-to-precipiton binding and would be inert to visible light in the absence of metals.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C11H10N2, you can also check out more blogs about56100-20-0
