H. Monobe et al., Carrier mobility of discotic lamellar mesophases of 5,10,15,20-tetrakis(4-n-pentadecylphenyl)porphyrin, CHEM LETT, (9), 2000, pp. 1004-1005
The carrier mobility of discotic lamellar mesophases was evaluated by Time-
of-Flight (TOF) method for mesogenic 5,10,15,20-tetrakis(4-n-pentadecylphen
yl)porphyrin and was found to be in the order of 10(-4) cm(2) V-1 s(-1). In
spite of the higher order of molecular orientation in the lamellar mesopha
ses, it is comparable with that of hexagonal disordered columnar mesophase.
This is the first report of charged carrier mobility of a discotic lamella
r mesophase.
