ModelImporterMaterialName.BasedOnTextureName
Description

Use material names in the form <textureName>.mat.

Material names will be accepted in the form <textureName>.mat (ie, the diffuse texture name of the imported material) when searching for existing materials or creating new ones.

If the imported material doesn't have a diffuse texture assigned then a name in the form <materialName>.mat will be used instead.
