A large-size 1-naphthol cluster, (1-NpOH)$$_{n}$$, with n=30 was prepared by using a high-pressure pulsed valve. The electronic and vibrational transitions of (1-NpOH)$$_{n}$$ with n=3-9 were measured by resonant two photon ionization (R2PI) and ion-detected IR dip spectroscopies. The (1-NpOH)$$_{3}$$ and the (1-NpOH)$$_{6}$$ clusters show relatively sharp origin bands. The structure of (1-NpOH)$$_{3}$$ was determined by comparison of the IR dip spectrum with the simulated one by DFT calculation, while those of (1-NpOH)$$_{n}$$ (n$$geq$$4) were discussed in terms of topological geometries of a hydrogen-bonded network. Those analyses suggest that (1) the (1-NpOH)$$_{3}$$ cluster has the cyclic structure where three 1-NpOH monomers are linked by both the hydrogen-bonding and the $$pi$$...C-H interaction between naphthyl rings and (2) the (1-NpOH)$$_{n}$$ cluster with n$$geq$$4 is built up by attaching the 1-NpOH monomers to the (1-NpOH)$$_{3}$$ core.
