Self-Assembly by Intermolecular Interaction Self-assembly on substrate External stimuli Covalent bond Substrate Hydrogen bond interactoion Van der Waals interaction Partoens, B. et al. Physical Review, 2011, 83, 165429 4
Condition of Substrate Ultra high vacuum (UHV) Merit ・No influence from air or moisture ・We can observe in wide temperature range. Demerit ・Molecule must be evaporated to deposit on surface. ・Complex manipulation. Liquid/solid interface Merit ・We can observe molecule at ambient condition. ・Easy manipulation. Demerit ・We can observe in narrow temperature range. ・Molecule must be dissolved in solvent. ５

Future Work hν Self-Assembly monomers Porous 2 D polymer 13
Conclusion ・To synthesize 2 D polymer I plan that monomers are ordered using self-assembly and linked by covalent bonding. ・I choose DBA as monomer. ・I planed that DBA alkoxy chains are linked using diacetylene topochemical reaction 14
