Communication: Spontaneous selective deposition of poly(p-phenylene vinylen
e) (PPV) by chemical vapor deposition is demonstrated for substrates treate
d with PPV-growth-inhibiting layers of iran. The Figure shows a Nomarski im
age of selectively grown parylene-N (squares) and PPV (black square spiral)
integrated onto the same substrate; the electroluminescent device shows sp
atially defined regions of luminescence.
