monolayer. Additional efforts are underway to transform
diyne shape-based, self-patterning monolayers into templates
for 1-D directed assembly of multi-component adlayers.
In conclusion, the shape self-repulsive nature of the
alkadiyne side chains [232;CRC-7,9] and [232;CRC-15,17] in
anthracenes 3 and 4 inhibits self-assembly of stable, single
component monolayers. The pairwise complementary shapes
of these side chains confers a large advantage to and directs
assembly of compositionally patterned, two component
monolayers. The assembly of patterned monolayers in complete
preference to single component domains establishes alkadiyne
side chain shape as a useful strategy for increasing structural
complexity of self-assembled monolayers.
