The Henry's Law constant for indole is estimated as 5.3X10-7 atm-cu m/mole (SRC) from its experimental values for vapor pressure, 0.0122 mm Hg (1), and water solubility, 3560 mg/l (2). This value indicates that indole will be essentially nonvolatile from water surfaces (3,SRC).It is shown that replacing branched side chains by linear ones in the BDT motifs induces a critical change in polymer self-assembly and backbone orientation in thin films that correlates with a dramatic drop in solar cell efficiency, making PBDTTPD one of the best polymer donors for use in the high-band-gap cell of tandem solar cells. While …
