A one pot synthesis of carbon dot incorporated porous coconut shell char derived sulphonated catalyst is reported here for the first time and is effectively used in the multicomponent synthesis of amidoalkyl naphthol. Macroporous nature of the char is revealed from scanning electron microscopic (SEM) analysis, whereas the dispersion of carbon dots (CDs) on the porous coconut shell char is confirmed from the high resolution transmission electron microscopic (HRTEM) analysis. Fluorescence emission spectrum further confirmed the presence of CDs in the catalyst. Fourier-transform infrared (FTIR) spectral analysis of the materials indicated that sulphonation occurred both to the CD and to the porous char. X-ray photo electron spectroscopic (XPS) analysis of the most active catalyst confirmed the presence of both sulphonic acid and carboxylic acid groups in the catalyst. The coconut shell char derived materials prepared by varying the amount of H₂SO₄ are successfully utilized as efficient alternative green catalysts for the multicomponent reaction, where excellent activity in amidoalkyl naphthol synthesis is obtained within short periods under solvent free reaction conditions. A maximum yield of 98% is obtained in the synthesis of N-[Phenyl-(2-hydroxy-naphthalen-1-yl)-methyl]-benzamide, the representative amidoalkyl naphthol, with the best catalyst within 3 min of reaction. The catalyst is highly active for the reactions carried out with varieties of aldehydes and amides with a product yield in the range of 88–98%. The best catalyst system retained more than 90% of its initial activity even upto 6^th repeated run.

首次报道了碳穴结合的多孔椰子壳炭衍生的磺化催化剂的一锅法合成，其有效地用于酰氨基烷基萘酚的多组分合成中。炭的大孔性质通过扫描电子显微镜（SEM）分析得到揭示，而碳点（CDs）在多孔椰子壳炭上的分散则通过高分辨率透射电子显微镜（HRTEM）分析得到证实。荧光发射光谱进一步证实了催化剂中CD的存在。对材料进行傅立叶变换红外（FTIR）光谱分析表明，磺化既发生在CD上，也发生在多孔炭上。活性最高的催化剂的X射线光电子能谱（XPS）分析证实了催化剂中同时存在磺酸基和羧酸基。通过改变H量制备的椰子壳炭衍生材料₂ SO ₄已成功地用作多组分反应的有效替代绿色催化剂，其中在无溶剂反应条件下，可在短时间内获得酰胺烷基萘酚合成中的出色活性。N- [苯基-（2-羟基-萘-1-基）-甲基]-苯甲酰胺，代表性的酰胺基烷基萘酚的合成，在反应3分钟内获得最佳催化剂，最大产率为98％。该催化剂对与各种醛和酰胺进行的反应具有很高的活性，产品收率在88–98％范围内。最好的催化剂体系甚至在^第6^次重复运行后仍能保持其90％以上的初始活性。
