title: Growth-controlled formation of porous coordination polymer particles.
abstract: Diversely shaped porous coordination polymer particles (CPPs) were synthesized by a simple solvothermal reaction of 1,4-benzenedicarboxylic acid (H2BDC) and In(NO3)3 x xH2O in DMF. The growth of crystalline CPPs was controlled through a particle growth blocking event involving blocking agent interaction with particular facets of CPPs and simultaneous particle growth interruption in a specific direction. Systematic reactions in the presence of various amounts of pyridine as a blocking agent were conducted to see the controlled CPP formation. Long rod, short rod, lump, and disk-shaped CPPs with hexagonal faces resulted in the presence of none, 1 equiv, 2 equiv, and 25 equiv of pyridine, respectively. The ultimate particle shape produced depends upon the amount of blocking agents used.
