Synthesis of Single-Crystal Tetra(4-pyridyl)porphyrin Rectangular Nanotubes in the Vapor Phase


Seok Min Yoon, In-Chul Hwang, Kwang S. Kim, and Hee Cheul Choi*

 

 

One-dimensional single-crystalline rectangular nanotubes (RNTs) of 5,10,15,20-tetra(4-pyridyl)porphyrin (H2TPyP, see picture) are synthesized by a vaporization-condensation-recrystallization process. The single-crystal X-ray diffraction and selected-area electron diffraction data reveal that the H2TPyP RNTs form by self-stacking of H2TPyP units through hydrogen-bonding, H-, and - intermolecular interactions. It attract investigating photo-physical properties such as waveguiding and lasing, amplified spontaneous emission, that the RNTs have good single crystallinity and high luminescence efficiency as well as can play a cavity.
