Abstract
The title compound [systematic name: 2-(benz-yloxy)naphthalene], C17H14O, which is used as a sensitiser for thermal paper, has a twisted conformation with a dihedral angle of 48.71 (12)° between the phenyl ring and the naphthyl ring system. In the crystal, one mol-ecule inter-acts with six neighbouring mol-ecules via inter-molecular C-H⋯π inter-actions to form a herringbone mol-ecular arrangement.

We found only one report on the crystal structure of a compound commonly used as a sensitiser for the thermosensitive layer (Rudolph et al, 2010), which can facilitate the dye coloration process by lowering the melting point of the dye/developer composite on thermal paper (US EPA, 2014)
Summary
Thermal printing is a rapid and inexpensive printing technology widely used in commercial applications such as receipts, faxes and tickets (Gregory, 1991; Mendum et al, 2011). Many structural reports are available for thermosensitive dyes and developers (Matsumoto et al, 2010; Kodama et al, 2013; Gontani et al, 2017; Ohashi et al, 2017). We found only one report on the crystal structure of a compound commonly used as a sensitiser for the thermosensitive layer (Rudolph et al, 2010), which can facilitate the dye coloration process by lowering the melting point of the dye/developer composite on thermal paper (US EPA, 2014). The title compound, benzyl 2-naphthyl ether, 1, is known as another commonly used sensitiser. We report the crystal structure of 1 as fundamental data for the investigation of its influence on the solid-state physicochemical properties of the thermosensitive layer of the thermal paper
