We find self-assembled structure of 3-fold symmetric tricarboxylic acid that is exclusively based on 3-fold H-bonds, which was predicted but remained elusive. Collaboration with @Sandeep_1966, @gakaur, @SSen_iitk, Markus Lackinger, Richa.

The carboxylic acid moiety gives rise to structural variability in surface-supported self-assembly due to the common expression of various H-bonding motifs. Self-assembly of 3-fold symmetric tricar...

We show by condensing a non-equilibrium state on surface, otherwise not possible in liquid state, confirmational switching efficiency of azobenzene derivatives can be increases by several folds.

A new class of pyridine-based spiropyran (SP) assembly on surface is switched quantitatively from the SP state to its merocyanine (MC) state by light. Using electrical-field a barrier less reversible switching is induced on single molecules at ambient conditions.

A very interesting molecule, taught us a beautiful chemistry at the interface of graphite and a few solvents. Thanks @berachm and his team for the wonderful collaboration.
Many lessons learned! Great to be a part of this collaboration with @tggopakumar1 and team. Solvent and Temperature Dependent Assembly in Monolayer Film of Ferrocene‐Naphthyridine Hybrid on HOPG
