Summary:PROBLEM TO BE SOLVED: To provide photochromic materials that can respond to electromagnetic radiation shifted to longer wavelengths.SOLUTION: This invention relates to, for example, an indeno-fused naphthopyran expressed by the following formula. The photochromic materials can have a closed-form electromagnetic radiation absorption spectrum that is shifted to longer wavelengths (e.g., wavelengths of greater than 390 nm), relative to comparable photochromic materials.SELECTED DRAWING: None 【課題】より長波長にシフトした電磁放射線に対応する、フォトクロミック材料の提供。【解決手段】例えば下記式で示されるインデノ縮合ナフトピラン。当該フォトクロミック材料は、比較可能なフォトクロミック材料と比較して、より長波長（例えば、３９０ｎｍより長い波長）にシフトした閉じた形態の電磁放射線吸収スペクトルを有し得る。【選択図】なし
