may be the same or different, in which the two alkoxy groups may be the same or
different or together represent an optionally substituted oxy-alkylene-oxy bridge;
a display comprising the above-mentioned electroluminescent device; a lamp comprising
the above-mentioned electroluminescent device; manufacturing processes for the
